S&W M&P Semi-Auto Pistols Quiz!

New Member

I am taking a self-passed and self-taught Armorers course and now I am on the S&W M&P Pistols. I hope to become a part-time light Gunsmith in the near future.

There are over 60 quiz questions covering this firearm and I have answered most of them hopefully correctly but during my study and research I am having some problems related to some of the following quiz questions. I have conflicting answers.

Can you help me determine the correct answers for these few quiz questions? Please correct my wrong answers!
